The adapter is designed to offer an inexpensive system that allows for the use of a vast range of lenses. Many lenses designed for DSLRs (particularly 85mm lenses and longer, most 50mm lenses and all tilt/shift lenses) produce image circles large enough to cover larger medium format sensors (though their performance will only have been optimized for their native formats). This adapter system is particularly useful for mounting tilt/shift lenses on the Fujifilm GFX Cameras, providing for an inexpensive alternative for shift photography.
